Vibrations are not sound as such. Sound is defined by the way that vibrations are perceived. Hence the riddle "If a tree were to fall in the forest and there were nothing around to hear it, would it make a sound?"
The sound we hear is our bodies way of detecting and analyzing these vibrations. Vibrations cause our ear drums to resonate with a frequency proportional to the vibration, giving us the frequency range of our hearing. This range may be determined by the physical properties of the ear drum or the brain just disregarding irrelevant information (this is more biological science than physical).
The brain analyses these vibrations via electrical signals that are sent from the ear drum. This is what we "hear". Our bodies have evolved to analyze the vibrations that affect our lives in an every day scenario i.e, a potential threat, finding food or a mate).
Many species have hearing ranges and accuities that are far superior to the human perception, such as bats, dogs, dear, and many others. Bats even generate ultrasonic vibrations and perceive the reflected ultrasonic frequencies well enough to navigate during flight.

Do tiny vibrations carry sound through the air?
Vibrations through some medium ARE sound. Vibrations through the air are just one example. The air vibrates and when the vibrations hit human ear drums, they are heard.
How do you explain sound to no hearing voice?
Explain vibrations, which they can feel. Then explain that sound is vibrations carried through the air.
How do you hear the sound coming from a drum?
Through sound waves travelling as vibrations through the air.
What is the speed of sound through milk?
Iron. The denser the material, the faster the waves can travel through it, because the vibrations carry faster. In addition, since milk is liquid, the motion of the liquid in response to the sound vibrations through air may absorb some of the waves.
How can sound transfer in liquid?
Same as in the air, through vibrations.
How does sound move through a medium?
Vibrations are carried through the atoms in a structure. When these vibrations travel through air, they are amplified by the ear drum and sensed by nerves as sound.
How are sound made?
Simply put, sounds are made through vibrations in the air. We can translate these vibrations into sound because of our ear drums.
How does the sound of a banjo travel through the air?
As vibrations, pressure waves.
Completes the sentence- Sound is caused by the movement of through the air. What movement is sound caused by?
vibrations
Why does sound need air?
Sound needs air because sound is the traveling of vibrations from one atom to another atom. In the vacuum of space, there are no gas particles or atoms for vibrations to travel through, which means there is no sound. Air has atoms in it (oxygen, hydrogen, and nitrogen atoms for the most part) that vibrations can travel through so we can hear sound so we do not have to press our ears to every object to hear its sound.
Why does sound travel in vibrations?
Because sounds are formed by vibrations, therefore there is no sound without vibrations. Furthermore, there is no vibrations without air. Consequently, sound needs air to vibrate forming waves of sound.
Does sound travel faster through a solid block of metal or through air?
Sound travels faster through air. Though sound travels farther through solid objects (vibrations), it is faster when traveling through air waves.
